IAG Revolve Engine Bay Dress-Up Cap Kit - 22-24 WRX, 13-21 BRZ, 22-24 BRZ

Get rid of the dull yellow plastic under your Subaru’s hood and upgrade your engine bay with the IAG Revolve Engine Bay Dress-Up Cap Kit. Compatible with 2022-2024 WRX and 2013-2024 BRZ Subaru models, these sleek anodized caps replace your factory oil, brake, clutch, coolant and washer caps with a more refined look—while maintaining a reliable, factory-quality seal.

All of the caps in the IAG Revolve Engine Bay Dress-Up Kit are precision-machined from 6061 billet aluminum for superior strength and heat resistance. Designed to outperform the factory plastic caps, each one is built to stand up to the harsh conditions under the hood. They feature a sleek anodized finish, providing enhanced corrosion resistance and a high-end appearance.

At the center of each cap is a sleek anodized aluminum insert, available in your choice of silver, red, blue, black, gold, or purple. Each insert is laser-etched with the appropriate universal symbol for each fluid system—oil, brake, clutch, washer and coolant, but can be flipped to show the solid color. The inserts are easy to swap in seconds, thanks to the accessible design inside each cap—just use a small tool to pop the insert out and choose your preferred side.

Designed for versatility, the IAG Revolve Engine Oil Fill Cap features a removable plug that can be replaced with an optional -10AN fitting. This allows you to run breather lines to a catch can such as our drag catch can, making it an ideal choice for those looking to improve crankcase ventilation or integrate a drain-back feature into a custom setup.

The IAG Revolve Brake Fluid Reservoir Cap is a step up from Subaru’s factory yellow plastic cap. Designed to withstand the heat of the engine bay, it resists the cracking and wear that can affect OEM caps over time. The result is trustworthy performance when it matters most, protecting against leaks and contamination.

OEM Subaru clutch fluid reservoir caps are designed with a breather vent to prevent airlocks, and the IAG Revolve Clutch Fluid Reservoir Cap retains that functionality while incorporating a more stylish and rugged anodized aluminum surround. No need to replace the factory cap—just install the lower portion of your OEM cap into the IAG housing for a secure fit. This upgrade enhances your engine bay’s appearance while ensuring the exact ventilation needed to prevent vacuum issues.

Like the rest of the IAG Revolve lineup, the Coolant Cap features durable billet aluminum construction and a clean, refined appearance. It’s a direct fit for the factory reservoir and provides a secure seal to help maintain pressure, prevent leaks, and support consistent coolant circulation.

The IAG Revolve Washer Cap is built to the same high standards as the rest of the Revolve series. It’s a direct replacement for the factory Subaru cap, but with a cleaner look, improved durability, and a dependable seal that keeps fluid in and debris out.
